Ankle-brachial index (ABI): measure brachial pressure bilaterally (use highest pressure) and measure pressure at ankle.
An abnormal ABI is defined as an index < 0.90. Values between 0.8 to 0.9 suggest some arterial disease. Values between 0.5 to 0.8 suggest moderate arterial disease. Values less than 0.5 is suggestive of severe arterial disease
Rest pain usually appears at an ABI < 0.3.
Solution: Trans-cutaneous oxygen studies to measure tissue oxygenation (30 mmHg necessary for primary wound healing). Doppler flow studies and real-time Duplex scanning
